Despite the pervasiveness of situation data such as incident report and situation report, we have the lack of a mothod for describing and analyzing situation data. In this research, the authors propose a new system for situational structure analysis by formulating situation analysis as a problem of graph structural analysis. The proposed system consistes of two basic functions: a function for graph-structuralizing and function for situation data-mining. The graph-structuralizing function allows users to create a semantic graph from free-description sentence on situation. The data-mining function allows users to conduct clustering and search similar situations. To prove the effectiveness of the developed system, we analyzed 818 child bicycle accident data.
